Concerns have been raised by both researchers and authorities regarding conspiracy theorists rejecting experts. To address the validity of these concerns, we need to delve into two key inquiries regarding who qualifies as an expert on conspiracy theories, and what constitutes an epistemically rational response (from a conspiracy theorist) when faced with expert testimony. The first inquiry presents a challenge when considering a reputationalist versus a realist account of experts. On the reputationalist account rejecting experts may be viewed as little (...) more than rejecting those whom society has collectively deemed as experts. Alternatively, adopting a realist account raises the challenge of determining who the genuine experts are. I argue that the realist account is the more compelling option for pursuing the first question. Moreover, I explore two prevalent accounts from existing literature that prescribe how epistemic agents should respond to expert testimony: the Preemptive View and the Community View. Through an examination using the simulation program Laputa, I demonstrate that both accounts are insufficient. Consequently, I argue that without a clear identification of experts in the broader context of conspiracy theories, the initial concern lacks a solid foundation, and the sense of urgency may be unwarranted.

Heterodox ideas face an uphill battle. This is not least the case for heterodox conspiracy theories. As an empirical observation, this is hardly controversial. What is controversial is whether and to what extent this should be the case. Some authors have gone so far as to argue that heterodox conspiracy theories should be generally dismissed, and that it is precisely their heterodox status that justifies such dismissal. Most particularists are likely to object strongly to such an assessment, arguing that conspiracy (...) theories – whether heterodox or orthodox – should not be dismissed before careful examination of the relevant evidence. But even particularists will probably concede that proponents of heterodox conspiracy theories have to bear a special epistemic burden. The main aim of this paper is to take a closer look at this particular epistemic burden. Drawing on the literature about peer disagreement, genealogical debunking arguments, and related philosophical debates, I focus in particular on the question of whether and under what conditions it can be rational to defend heterodox conspiracy theories, and argue that what I will call theories of error play a crucial role in this context.
